Abstract: A new first-order configuration simultaneously implementing LP, HP, and AP filtering functions is presented. The circuit is based on and employs two CCIIs, two floating, two grounded resistors, and one grounded capacitor. The topology of the circuit is amenable for construction using translinear conveyors (CCCII) also. This version of the circuit facilitates electronic control of cutoff frequency besides offering saving in components as it employs only one capacitor and two resistors instead of five passives. The realizability condition for allpass response is simple and temperature independent. The circuit enjoys low sensitivity figures. The, PS (PSPICE) PICE simulation is obtained confirming the theoretical analysis.
